Compile subroutine Create_Table_In_SQL(Table, GenerateCodeOnly)
|
||||
|
||||
/*****************************************************************************\
|
||||
This is a utility function. Using the table's dictionary, it creates a
|
||||
basic matching table in the SQL database, omitting explicit multivalue and
|
||||
symbolic fields. Simply makes work a little faster.
|
||||
|
||||
PARAMETERS:
|
||||
Table - The table for which code and sql tables are to be
|
||||
created.
|
||||
GenerateCodeOnly - Set to 1 to generate code and not sql tables. Set to 2
|
||||
to generate delete code only and not sql tables.
|
||||

||||
History
|
||||
-------
|
||||
04/12/2010 KRF Original Programmer
|
||||
04/22/2010 KRF Added logic to rename DESC to DESCRIPTION to avoid SQL
|
||||
errors
|
||||
07/12/2010 KRF Updated to handle multiple primary keys
|
||||
09/08/2010 KRF Swapped FIELDCOUNT with field count + 1 to make sure
|
||||
records with undocumented extra fields do not cause
|
||||
the SQL statements to fail.
|
||||
09/21/2010 KRF Added support for generating DELETE subroutine
