sqlipExecuteStmt

This method is called to execute both SELECT and non-SELECT prepared statements.

For statements that result in a cursor, the IP executes the statement and opens the cursor to the first row. Return the number of rows selected in the piNumResRows parameter. If the number of rows selected cannot be determined at this time, then return -1. Call sqlipCloseCursor when all rows have been fetched or when the application closes the statement.

For statements that update the data (such as INSERT, UPDATE, and DELETE), the IP executes the statement, returns in piNumResRows the number of rows affected, and returns 0 for the number of columns in the cursor when sqlipGetNumcols is called.

A sqlipCloseCursor method is called only when columns are returned.
