插入與選擇

Question

你好，我想從一個SELECT查詢

insert into (cmts) stat_alert 
values(SELECT stat_alert.cell,stat_alert.cmts,cell_cmt.cmts FROM stat_alert`LEFT OUTER JOIN cell_cmt ON cell_cmt.`cell`=stat_alert.cell WHERE stat_alert.`cell`=cell_cmt.cell) 

插入一列中的值我有語法錯誤 誰可以幫我？

Answer 1

你不需要VALUES關鍵字和圓括號：

INSERT INTO <table name> (<comma separated column list>) 
SELECT <comma separated column list> FROM <table name> 

閱讀INSERT ... SELECT syntax from the manual。

Answer 2

你想用INSERT INTO otherTable (cols) SELECT <yourColumns> FROM <yourtable>不INSERT INTO ... VALUES()：

insert into stat_alert (cmts) -- list your columns here to insert into 
SELECT cell_cmt.cmts -- your values to be inserted are here 
FROM stat_alert 
LEFT OUTER JOIN cell_cmt 
    ON cell_cmt.`cell`=stat_alert.cell 
WHERE stat_alert.`cell`=cell_cmt.cell 

Answer 3

它看起來像您有：

1. 表名前的列列表
2. 一列插入，但三列選擇
3. A values關鍵字當這種查詢中不需要任何關鍵字時。
