Question

我的代码是：下面是我的光标声明，但它显示错误1324：未定义光标为什么？请帮帮我

 Set v_sqlCmd1 = CONCAT('DECLARE endtCursor Cursor for Select endorsementId from TxnEndorsement where txnRecNo=' + Cast(p_txnRecNo As char (20)));
        SET @stmt_str =  v_sqlCmd1;
        PREPARE stmt FROM @stmt_str;
        EXECUTE stmt;
        DEALLOCATE PREPARE stmt;

        OPEN endtCursor;//shows  error 1324:undefined endtCursor

是否有错误来取消游标？

Answer 1

如果我没有错，你试图在MYSQL中编写存储过程问题不在于Cursor。

由于您尚未粘贴整个存储过程，

标准存储过程就像这样

drop procedure if exists procname;
delimiter $$

create procedure procname
(
in arg int default 0
)
begin    
## Do the operations you want here your cursor and whatever    
end$$

delimiter ;

我建议粘贴整个存储过程！希望有所帮助。

看起来好像你还没有完全问过这个问题，但游标的语法看起来应该类似于：

Sub addEquals
    oDoc = ThisComponent
    oVC = oDoc.getCurrentController.getViewCursor
    linenum_original = getLinenum(oVC)
    For insertEqual = 1 to 255
        oVC.collapseToEnd
        oVC.gotoEndofLine(False)
        oVC.getText().insertString(oVC, "=", False)
        If getLinenum(oVC) <> linenum_original Then
            ' Remove the last =
            oVC.gotoEndofLine(False)
            oVC.goLeft(1, True)
            oVC.setString("")
            oVC.goRight(0, False)
            oVC.collapseToEnd
            Exit For
        End If
    Next insertEqual
End Sub

Function getLinenum(oVC)
    nY = 0  'How many lines from top of page
    nPage = oVC.getPage
    while oVC.goUp(1, False) and oVC.getPage = nPage
        nY = nY + 1
    wend
    oVC.goDown(nY, False)
    getLinenum = nY
End Function

错误1324：mysql中未定义的游标
