Change subject: res_odbc.h: Added StrLen_or_IndPtr for use in SQLBindParameter
......................................................................


Patch Set 1:

Whats version of Ignite is affected?

According to ODBC specification

https://docs.microsoft.com/en-us/sql/odbc/reference/syntax/sqlbindparameter-function?view=sql-server-ver15#strlen_or_indptr-argument
"If StrLen_or_IndPtr is a null pointer, the driver assumes that all input parameter values are non-NULL and that character and binary data is null-terminated."

https://www.ibm.com/support/knowledgecenter/en/SSEPEK_11.0.0/odbc/src/tpc/db2z_fnbindparameter.html
"If the fCType argument indicates character data (explicitly, or implicitly with SQL_C_DEFAULT), and the pcbValue argument is set to NULL, it is assumed that the application always provides a nul-terminated string in the buffer to which the rgbValue argument points. This null setting also implies that the parameter marker never uses null values."

I think it was fixed in Ignite v2.3
https://issues.apache.org/jira/browse/IGNITE-6211
"ODBC: SQLBindParameter should not unbind parameter if the ParameterValuePtr is NULL"
