Note: This function requires the external module lu_sqlite.
This function returns the next result row of the query result struct. If the query has no more result rows the function will return null, otherwise it will return a pointer to the next row.
[edit] Syntax
UserPointer sqlite_next_row( UserPointer result )
[edit] Arguments
- result - This is a pointer to a result struct retrieved from sqlite_query or another iteration of sqlite_next_row
[edit] Example
This will see if anymore data is in the results when 'nextrow' is typed into the server console.
function onScriptLoad() { LoadModule( "lu_sqlite" ); pSQDatabase <- sqlite_open( "database.sqlite" ); return 1; } function onConsoleInput( szCommand, szText ) { if ( szCommand == "nextrow" ) { local query = sqlite_query( pSQDatabase, "SELECT Foo FROM Bar WHERE FooBar='" + szText + "'" ); if ( query ) { local data = sqlite_column_data( query, 0 ); if ( data ) { print( "Result: " + data ); local data2 = sqlite_next_row( data ); if ( data2 ) print( "Result 2: " + data2 ); else print( "No moar data found!" ); } else print( "No data found!" ); } } return 1; }
[edit] Notes
The function LoadModule and sqlite_open and sqlite_query and print and event onScriptLoad and onConsoleInput were used in this example. More info about them in the corresponding pages.
For a larger example, check the SQLite database example from the wiki tutorials.
