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.
Syntax
DBCursorGetValue( numCur, strColumn, "optStrErrorTag" )
- numCur
- The cursor handle for the result set. The cursor
handle is returned by
DBCursorOpen or
DBCursorOpenSQL.
- strColumn
- The name of the column.
- optStrErrorTag
- The name of a String tag that will receive detailed
error messages, if errors occur during runtime.
Note: The tag
name must be enclosed in quotes, as shown in the syntax diagram, or
else the project will try to get the value of the named tag.
This is an optional parameter.
Returned value
Returns the value of the specified column. If the
value is NULL or the cursor is invalid, then it returns an empty
string with quality BAD.
