FMDB SQLite question: row count of a query?

Question

does anyone know how to return the count of a query when using FMDB? If I executeQuery @\"select count(*) from sometable were...\" I get an empty FMResultSet back. How can I get

Answer 1

try this. It works for me. Iterating all the records is not recommended.

FMResultSet *rs = [db executeQuery:@"select count(FIELD) as cnt from TABLENAME"];
while ([rs next]) {
    NSLog(@"Total Records :%d", [rs intForColumn:@"cnt"]);
}

May be you should check your Where clause.

Answer 2

If you want to know the count of the rows before make something with the result, you can even do a simple query and ask for the results columnCount that give you the number of rows and you can save one query if you really want to make something with the resultSet

FMResultSet *results = [database executeQuery:@"SELECT * from tableName"];
int numberOfRows = [results columnCount];

while ([results next]){
... do your stuff ...
}
