this function was created to support
OUTPUT parameters and return values with
MSSQL stored procedures. Before this,
you could use T-SQL statement EXECUTE
and mssql_query to execute a stored
procedure, and it was fine as long as
you don't need to retrieve OUTPUT or
RETVAL values.
Now you can use this set of functions to execute and retrieve these
values:
mssql_init
mssql_bind
mssql_execute
Parameters:
- sp_name : stored procedure name. It passes this string to a native DB-lib
call, so I guess it supports all kinds of schemas (like
"ownew.sp_name" or "otherdb.owner.sp_name")
- connection id: a connection resource
obtained with mssql_connect or similar.
If not provided, it will proceed just
like other similar mssql_* functions:
uses a default open connection or
creates a new one.
Return value: a resource id, called
"statement", used in subsequent calls to
mssql_bind and mssql_execute.
Note that many of the native MSSQL data types are directly supported, but I
think that some others must be converted
by other means (from varchar values for
example). These unsupported types are:
SQLMONEY4,SQLMONEY,SQLBIT,SQLDATETIM4,
SQLDATETIME, SQLDECIMAL, SQLNUMERIC,
SQLVARBINARY, SQLBINARY,SQLIMAGE
