試圖將圖像插入到sql server中,並且需要將圖像作爲base64格式。我正在接受例外。請讓我知道什麼類型的數據類型以及如何在sql server中以base64的形式插入圖像。嘗試將Base64圖像插入到sql server數據庫中
輸出:
INSERT INTO test (image) VALUES ([[email protected])
java.sql.SQLException: Invalid SQL statement or JDBC escape, terminating ']' not found.

']'沒有找到,所以在價值觀像結尾處添加']'到您的查詢([B @ 7229724f']') –
@ZaidYasyaf謝謝,你用這個建議讓我的日子過得很開心 – Andremoniy
爲什麼你想要Base64首先對字節進行編碼?你會浪費不必要的空間。 – Kayaman
