Note: This feature emulates SQL (Structured Query Language) database operations. You should be familiar with how SQL commands are formed and executed before you use this feature.


  DBCursorColumnInfo( numCur, numColumn, numTypeInfo, "optStrErrorTag" )  
The cursor handle of the result set. The cursor handle is returned by DBCursorOpen or DBCursorOpenSQL.
The number of the column about which you want to get information. Remember that a result set may include only some of the columns in the original database table.
The type of information you want to get about the column:
Value Description
0 Column name
1 Column data type
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

In case of error, returns a negative number. Otherwise, returns 0.


You can use the Studio Database Gateway to directly monitor database connections for leaks and errors. For more information, see Database Interface.
