Question

我在log cat中得到一个SQLite异常，说明＆＃34; ANDcontraYesOrNo＆＃34;附近存在语法错误。

Cursor c = db.query( VivzHelper.TABLE_NAME, columns, helper.TX_IDT+"     
='"+name+"' AND" +helper.CONTRA_YES_OR_NO+ "='"+contraY+"' 
OR"+helper.CONTRA_YES_OR_NO+"='"+contraN+"'" +"",null,null, null, NAME + " 
ASC");

logcat的：

 at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:641)
    at dalvik.system.NativeStart.main(Native Method)
    Caused by: android.database.sqlite.SQLiteException: near "ANDcontraYesOrNo":     
    syntax error (code 1): , while compiling: SELECT _id, name FROM outtable 
    WHERE txidt ='I' ANDcontraYesOrNo='Y' ORcontraYesOrNo='N' ORDER BY name ASC

Answer 1

在AND和OR导致

之后添加空格

Cursor c = db.query( VivzHelper.TABLE_NAME, columns, helper.TX_IDT+"     
='"+name+"' AND " +helper.CONTRA_YES_OR_NO+ "='"+contraY+"' 
OR "+helper.CONTRA_YES_OR_NO+"='"+contraN+"'" +"",null,null, null, NAME + " 
ASC");

cursor query为where子句和/或where子句提供语法错误
