爲什麼我在這個Sql字符串中出現'Data Type Mismatch'錯誤？

Question

我使用Visual Basic快訊2010年和我使用的是Access數據庫

Dim count as Integer

SQL = "SELECT * FROM transac WHERE transac_id = " & "'" & count & "'"

Answer 1

我會假設你transac_id是INT數據類型，並且您將周圍的單引號count使它成爲一個字符串。

嘗試：

SQL = "SELECT * FROM transac WHERE transac_id = " & count 

Answer 2

"select * from transac where transac_id = " & count;
