How do you get table name from count query, I have multiple queries and I need to get table name from the query results, here is my query
$myquery = "select count(tb_id) as num_rows from table1; select count(tb1_id) from table2...";
if (myqli_multi_query($connection, $myquery){
..
$row = mysqli_fetch_assoc($result);
$num_rows = $row["num_rows"];
..
}
The query is working fine as I can get the number of rows, but I am unable to link the table name to the number of rows (result)
I have tried this, which executes without error, but unable to get the table name still
select count(tb_id) as num_rows, 'table1' as TableName from table1
You could put an identifier into your query you can refer to later.
$myquery = "select 'table1' as tablename, count(tb_id) as num_rows from table1;
select 'table2' as tablename, count(tb1_id) as num_rows from table2;"
// and so on
Just add it in to the select or the column name.
Column name:
select count(tb_id) as table1_count from table1; select count(tb1_id) as table2_count from table2.
OR sep column:
(select count(tb_id) as num_rows, 'table1' as tablename from table1)
UNION
(select count(tb1_id), 'table2' from table2...)
UNION.... etc
Edited to add: you are returning sep resultsets; consider UNION above for a single resultset.
您可以尝试mysqli_fetch_field
mysqli_fetch_field($result)->table;
