   With SQL_C_BINARY copies also the terminating byte '\0' into the

   stores there a value which is one less. (terminating byte '\0'
   excluded).

   13-MAR-1997 AK  Changed back to the habit of excluding the termination
   byte '\0' from the copied stuff and from the length of it when copying
   stuff in SCL_C_BINARY format.

   Note how in *len_ret is always returned the original length of dv data
   (possibly - 1 if SQL_C_CHAR) without subtracting str_from_pos from it.

   This comment is from ODBC API Help File, please keep it here for

   Converting timestamp SQL data to SQL_C_CHAR
   and converting DATE's and TIME's to anything...

   rgbValue	  pcbValue	SQL-STATE

   cbValueMax > Dispsize	 Data	      Length of data   N/A
   20 <= cbValueMax <= Dispsize  Truncated data b, Length of data??? 01004
   cbValueMax < 20		 Untouched	 Untouched	22003

   I guess Dispsize (Display size) means here 29 ?

   What does Length of data in the second case (when it is truncated)
   mean? The length before or after truncation?

   In the second case fractional seconds of the timestamp are truncated.

   When timestamp SQL data is converted to character C data, the resulting
   string is in the "yyyy-mm-dd hh:mm:ss[.f...]" format, where up to nine
   digits may be used for fractional seconds. (Except for the decimal point
   and fractional seconds, the entire format must be used, regardless of
   the precision of the timestamp SQL data type.)


   =======================================
   SQL to C: Date
   =======================================

   The date ODBC SQL data type is:

   SQL_DATE

   The following table shows the ODBC C data types to which date SQL data
   may be converted.

   fCType	   Test		      rgbValue    pcbValue  SQL-STATE
   SQL_C_CHAR       cbValueMax >= 11	  Data	10	N/A
   cbValueMax < 11	   Untouched   Untouched 22003
   SQL_C_BINARY  Len of data <= cbValueMax Data	Length of data N/A
   Len of data > cbValueMax  Untouched   Untouched 22003
   SQL_C_DATE	None a		    Data	6 c       N/A
   SQL_C_TIMESTAMP       None a		    Data b      16 c      N/A

   a The value of cbValueMax is ignored for this conversion.
   The driver assumes that the size of rgbValue is the size
   of the C data type.

   b The time fields of the timestamp structure are set to zero.

   c This is the size of the corresponding C data type.
   (I.e. DATE_STRUCT (size 6) and TIMESTAMP_STRUCT (size 16) defined
   in sqlext.h)

   When date SQL data is converted to character C data, the resulting
   string is in the "yyyy-mm-dd" format.

   =======================================
   SQL to C: Time
   =======================================

   The time ODBC SQL data type is:

   SQL_TIME

   The following table shows the ODBC C data types to which time SQL
   data may be converted.

   fCType	   Test		      rgbValue   pcbValue  SQL-STATE
   SQL_C_CHAR	cbValueMax >= 9	   Data       8	 N/A
   cbValueMax < 9	    Untouched  Untouched 22003
   SQL_C_BINARY     Len of data <= cbValueMax Data       Length of data N/A
   Len of data > cbValueMax  Untouched  Untouched 22003
   SQL_C_TIME       None a		    Data       6 c       N/A
   SQL_C_TIMESTAMP       None a		    Data b     16 c      N/A

   a The value of cbValueMax is ignored for this conversion. The driver
   assumes that the size of rgbValue is the size of the C data type.

   b The date fields of the timestamp structure are set to the current
   date and the fractional seconds field of the timestamp structure is
   set to zero.

   c This is the size of the corresponding C data type.
   (I.e. TIME_STRUCT (size 6) and TIMESTAMP_STRUCT (size 16) defined
   in sqlext.h)

   When time SQL data is converted to character C data, the resulting
   string is in the "hh:mm:ss" format.

   The meaning of SQL states 01004 and 22003 are:

   01004   Data truncated  The data returned for one or more columns was
   truncated. String values are right truncated. For numeric values,
   the fractional part of number was truncated.
   (Function returns SQL_SUCCESS_WITH_INFO.)

   22003   Numeric value out of range   Returning the numeric value
   (as numeric or string) for one or more columns would have
   caused the whole (as opposed to fractional) part of the number
   to be truncated.
   Returning the binary value for one or more columns would have
   caused a loss of binary significance. For more information,
   see Converting Data from SQL to C Data Types.

   Currently (version 0.99b 31-MAR-1997 and earlier versions) we are liberal,
   we never use state 22003 so that the client can grab as short piece of
   e.g. timestamp or date as (s)he ever wants.
   E.g., by using cbValueMax 11 the client can take just the date portion
   from the timestamp, if he is unable to supply SQL type info (SQL_DATE)
   here, as is case e.g. with SQLBindCol or SQLGetData, when sql_type will
   be simply zero.

    Now dv_to_place returns a length of the copied piece, normally
    same as what is stored to len_ret, except if the argument is of
    certain boxed types like strings or timestamps, etc, and less than
    the whole length is copied.
    Currently only SQLGetData uses this return value for anything.

    If dv_value 'it' is XXX, returns YYY and stores ZZZ to *len_ret

    NULL	 SQL_NULL_DATA  SQL_NULL_DATA
    box of length zero   SQL_NULL_DATA  0

    If max is 0 (c_type is
    SQL_C_BINARY or SQL_C_CHAR)
    or max is 1 and c_type
    is SQL_C_CHAR	   returns 0   and stores zero to *len_ret
    (in case c_type is SQL_C_CHAR and string is '')
    returns 0   and stores non-zero to *len_ret
    (in all other cases)

    If max is greater than 0 (with SQL_C_BINARY) or 1 (with SQL_C_CHAR)
    returns length of piece copied and stores to
    *len_ret the whole length of dv box (with
    SQL_C_BINARY) or one less (SQL_C_CHAR).

    If max is 777 and c_type is SQL_C_CHAR and box is '' (i.e. one byte '\0')
    then copies the terminating byte to place, returns zero, and stores
    zero to *len_ret.

    Otherwise, returns the size of data type (in bytes) and stores the
    same value to *len_ret (if len_ret is not NULL).

    Note how in *len_ret is always returned the original length of dv data
    (possibly - 1 if SQL_C_CHAR) without subtracting str_from_pos from it.
    It is the task of SQLGetData to calculate and store the correct value
    into its pcbValue pointer argument.

   11.1 SQL Escape Syntax

   JDBC supports the same DBMS-independent escape syntax as ODBC for stored
   procedures, scalar functions, dates, times, and outer joins. A driver
   maps this escape syntax into DBMS-specific syntax, allowing portability
   of application programs that require these features. The DBMS-independent
   syntax is based on an escape clause demarcated by curly braces and a
   key-word:
   {keyword ... parameters ...}

   This ODBC-compatible escape syntax is in general not the same as has
   been adopted by ANSI in SQL-2 Transitional Level for the same
   functionality. In cases where all of the desired DBMSs support the
   standard SQL-2 syntax, the user is encouraged to use that syntax instead
   of these escapes. When enough DBMSs support the more advanced SQL-2 syntax
   and semantics these escapes should no longer be necessary.

   11.2 Stored Procedures

   The syntax for invoking a stored procedure in JDBC is:

   {call procedure_name[(argument1, argument2, ...)]}

   or, where a procedure returns a result parameter:

   {?= call procedure_name[(argument1, argument2, ...)]}


   11.3 Time and Date Literals

   DBMSs differ in the syntax they use for date, time, and timestamp literals.
   JDBC supports ISO standard format for the syntax of these literals, using
   an escape clause that the driver must translate to the DBMS representation.
   For example, a date is specified in a JDBC SQL statement with the syntax
   {d ‘yyyy-mm-dd’}
   where yyyy-mm-dd provides the year, month, and date, e.g. 1996-02-28.
   The driver will replace this escape clause with the equivalent
   DBMS-specific representation, e.g. ‘Feb 28, 1996’ for Oracle.

   There are analogous escape clauses for TIME and TIMESTAMP:

   {t ‘hh:mm:ss’}
   {ts ‘yyyy-mm-dd hh:mm:ss.f...’}

   The fractional seconds (.f...) portion of the TIMESTAMP can be omitted.

   11.4 Scalar Functions

   JDBC supports numeric, string, time, date, system, and conversion
   functions on scalar values.
   These functions are indicated by the keyword fn followed by the name of
   the desired function and its arguments. For example, two strings can be
   concatenated using the concat function

   {fn concat('Hot', 'Java')}

   The name of the current user can be obtained through the syntax
   {fn user()}

   11.5 LIKE Escape Characters

   The characters % and _ have special meaning in SQL LIKE clauses
   (to match zero or more characters, or exactly one character, respectively).
   In order to interpret them literally, they can be preceded with a special
   escape character in strings, e.g. \. In order to specify the escape
   character used to quote these characters, include the following syntax
   on the end of the query:

   {escape 'escape-character’}

   For example, the query
   SELECT NAME FROM IDENTIFIERS WHERE ID LIKE ‘\_%’ {escape ‘\’}
   finds identifier names that begin with an underline.

   11.6 Outer Joins

   The syntax for an outer join is

   {oj outer-join}

   where outer-join is of the form
   table LEFT OUTER JOIN {table | outer-join} ON search-condition

/* convert_brace_escapes: a lazy attempt to implement the balderash above,
   started by AK 3-3-1997.
   Called from SQLPrepare and SQLExecDirect (in module wicli.c)

   Currently only the first case, invoking of a stored procedure is
   supported. That is, just brutally wipes off the beginning and
   ending curly braces, if they are the first and last non-white-space
   characters of the statement_text respectively.
   Does this in place, modifying destructively its string argument,
   which is returned back as a result.
   This should not affect any statements naturally containing
   curly braces, whether inside string literals, or as a part of
   procedure definitions.

   Note that the cases
   {d 'date-string'} {t 'time-string'} {ts 'timestamp-string'}
   {fn function-call} and {escape 'escape-char;}
   are now handled in server end (see sql2.y), and that leaves
   only {?=call fun(...)} which should be also implemented later
   in the server end, as well as {oj ...} for outer-joins, also
   sensible to implement in the server. Maybe this whole function
   will become unnecessary later.
