Syntax
DBCursorCurrentRow( numCur, "optStrErrorTag" )
- numCur
- The cursor handle of the result set. The cursor handle is returned by DBCursorOpen or DBCursorOpenSQL.
- optStrErrorTag
- The name of a String tag that will receive detailed error messages, if errors occur during runtime.
Note: The tag name should be enclosed in quotes, as shown in the syntax diagram, or else the function will try to use the value of the tag.
This is an optional parameter.
Returned value
Returns the number of the current row. In case of error, returns a negative number.
Notes
You can use the Studio Database Gateway to directly monitor database connections for leaks and errors. For more information, see Database Interface.
