我有一个表,其中包含一个COUNT()函数,该函数返回所有字段并对它们进行计数。现在,我需要连接另一个表,并返回匹配的行数和不匹配的行数。我不太确定如何使用GROUP BY和COUNT()函数来获得所需的结果。SELECT tb1.type, count(tb1.type) as totalGROUP BY tb1.typeTABLE1的结果:
Type
" ", $label);//split the label to a array//.....insert another data, getting the $last_id here
for ($i =0; $i< count($splitLabel); $i++){
if ($i < count($splitLabel)){$sql .= "INSERT IN
我想数一数每一种状态的人数,所以我会有一张表看起来像45 27 9 49 (SELECT COUNT(*) AS 'StatusHW' FromHomeworkerStatus WHERE Status='Homeworker') (SELECT COUNT(*) AS 'StatusHB' FromHomeworkerStatus WHERE Status='Home Based'
我新来处理sql,我对此很感兴趣 @MAESTRDESC varchar(50) --Contiene el valor a ingresarResult TABLE ClientesDisponibles int, ) @SQLvarchar(500),--Guarda la cantidad de clientes disponibles
