Обсуждение: Passing numeric Bind variables to ODBC driver convers to "Double precision"

 Using the lastest of ODBC ANSI driver for windows 32bit ver 9.00.03  Calling from MS VFP 9.0

 public nvar as interger
 nvar=1
 running the following sql:
 "( select function_pkg(?nvar) "

 The bind variable nvar will show in postgres as "Double Precision"  format instead of integer(or numeric)

 Is there a setting on the ODBC driver for incoming vairables?

Are you turning on the Server side prepare option?

Thanks, "UseServerSidePrepare=1;  does appear to fix this. (working for both numeric and integer)

Next issue,
When calling a function in postgres, the postgres is returning a blank string ('').
This is showing as a blank longvarchar(memo,clob) instead of a varchar.

Any ideas?
 
Thanks

Please try to turn off the Text as LongVarChar option.

Note: The UseServerSidePrepare=1; only works with the PostgresSQL 9.01 driver (It will not work with the 9.00 driver)

Setting TextAsLongVarchar=0 has no effect on the blanks("") comes back as longvarchar.

UnknownsAsLongVarchar=0 or UnknownsAsLongVarchar=1 has no effect on this either.

Could you send me the Mylog output?
You can take the log by adding Debug=1; in your connection string.
