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?
Answer:
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());
}
