SQLStatement.execute() - multiple queries in one statement


I've written a database generation script in SQL and want to execute it in my Adobe AIR application:

Create Table tRole (
    roleID integer Primary Key
    ,roleName varchar(40)
);
Create Table tFile (
    fileID integer Primary Key
    ,fileName varchar(50)
    ,fileDescription varchar(500)
    ,thumbnailID integer
    ,fileFormatID integer
    ,categoryID integer
    ,isFavorite boolean
    ,dateAdded date
    ,globalAccessCount integer
    ,lastAccessTime date
    ,downloadComplete boolean
    ,isNew boolean
    ,isSpotlight boolean
    ,duration varchar(30)
);
Create Table tCategory (
    categoryID integer Primary Key
    ,categoryName varchar(50)
    ,parent_categoryID integer
);
...

I execute this in Adobe AIR using the following methods:

public static function RunSqlFromFile(fileName:String):void {
    var file:File = File.applicationDirectory.resolvePath(fileName);
    var stream:FileStream = new FileStream();
    stream.open(file, FileMode.READ)
    var strSql:String = stream.readUTFBytes(stream.bytesAvailable);
    NonQuery(strSql);
}

public static function NonQuery(strSQL:String):void {
    var sqlConnection:SQLConnection = new SQLConnection();
    sqlConnection.open(File.applicationStorageDirectory.resolvePath(DBPATH));
    var sqlStatement:SQLStatement = new SQLStatement();
    sqlStatement.text = strSQL;
    sqlStatement.sqlConnection = sqlConnection;
    try {
        sqlStatement.execute();
    } catch (error:SQLError) {
        Alert.show(error.toString());
    }
}

No errors are generated, however only tRole exists. It seems that it only looks at the first query (up to the semicolon- if I remove it, the query fails). Is there a way to call multiple queries in one statement?


Solution

  • I wound up using this. It is a kind of a hack, but it actually works pretty well.

    The only thing is you have to be very careful with your semicolons. : D

    var strSql:String = stream.readUTFBytes(stream.bytesAvailable);      
    var i:Number = 0;
    var strSqlSplit:Array = strSql.split(";");
    for (i = 0; i < strSqlSplit.length; i++){
        NonQuery(strSqlSplit[i].toString());
    }
