SQL如果在腳本中存在

如果這是在錯誤的區域，請直接指向我所在的區域我正在使用Ignition BY inductiveautomation，並嘗試編寫一個腳本，該腳本將基於如果存在條件。我有一個查詢將插入一個新的記錄到我下面列出的數據庫，但現在我想能夠更新「設置表」，如果它已經存在。SQL如果在腳本中存在

Code: 
queryValue1 = event.source.parent.getComponent('MoldName').selectedStringValue 
queryValue2 = event.source.parent.getComponent('MachineName').selectedStringValue 
queryValue3 = event.source.parent.getComponent('Text Area').text 
if system.gui.confirm("Steve! Are you sure you want to Save changes?", 
    "Save Changes"):  
     system.db.runPrepUpdate("INSERT INTO setup_sheetlist (MoldName,machineName,Setupsheet) VALUES ('%s','%s','%s')" % (queryValue1, queryValue2 , queryValue3), getKey=1)

這是我的查詢，它在我的數據庫的工作，但我失去的就如何落實到了RunPrepUpdate，

Code: 
    IF EXISTS(SELECT * FROM setup_sheetlist WHERE moldname='100SCX-3' AND Machinename='MM11') 
     UPDATE setup_sheetlist 
     SET setupsheet ='updated value 3' 
     WHERE moldname='100SCX-3' AND Machinename='MM11' 

    ELSE 
      INSERT INTO setup_sheetlist(MoldName,machineName,Setupsheet) 
      VALUES('100SCX-3','MM11','TRIAL 2')

這是我到目前爲止，這給了我一個錯誤消息

queryValue1 = event.source.parent.getComponent('MoldName').selectedStringValue 
queryValue2 = event.source.parent.getComponent('MachineName').selectedStringValue 
queryValue3 = event.source.parent.getComponent('Text Area').text 
if system.gui.confirm("Steve! Are you sure you want to Save changes?", 
    "Save Changes"):   

      system.db.runPrepUpdate("IF EXISTS(SELECT * FROM setup_sheetlist WHERE moldname='?' AND Machinename='?')UPDATE setup_sheetlist SET setupsheet ='?' WHERE moldname='?' AND Machinename='?'" ,[queryValue1,queryValue2,queryValue3,queryValue1,queryValue2]) 
      ELSE 
      INSERT 
      INTO 
      setup_sheetlist (MoldName,machineName,Setupsheet) 
      VALUES ('%s','%s','%s')" % (queryValue1, queryValue2 , queryValue3))

錯誤

我懷疑你沒有得到queryValue1＆queryValue2的任何值。你可以運行print語句來驗證runPrepUpdate之前的變量是什麼嗎？ –

@TabAlleman，在添加if之前，查詢value1＆2與insert語句一起工作 – Jad

我應該在查詢結束一次全部通過了變量，而不是它打破零件的。

system.db.runPrepUpdate("IF EXISTS(SELECT * FROM setup_sheetlist WHERE moldname=? AND Machinename=?)UPDATE setup_sheetlist SET setupsheet =? WHERE moldname=? AND Machinename=? ELSE INSERT INTO setup_sheetlist (MoldName,machineName,Setupsheet) VALUES (?,?,?)" , (queryValue1,queryValue2,queryValue3,queryValue1,queryValue2,queryValue1, queryValue2 , queryValue3))
