Create a DSN
To create a Data Source Name (DSN) go to Administrative Tools > Data Sources (ODBC).
Create the DSN on the tier where the X++ code will call the DSN from. This will be either on the client computer or on the AOS computer.
X++ Code Example with ODBC
// X++ job
static void TestOdbcJob()
{
LoginProperty loginProperty;
OdbcConnection odbcConnection;
Statement statement;
ResultSet resultSet;
str sql, criteria;
SqlStatementExecutePermission perm;
;
// Set the information on the ODBC.
loginProperty = new LoginProperty();
loginProperty.setDSN("dsnName");
loginProperty.setDatabase("databaseName");
//Create a connection to external database.
odbcConnection = new OdbcConnection(loginProperty);
if (odbcConnection)
{
sql = "SELECT * FROM MYTABLE WHERE FIELD = "
+ criteria
+ " ORDER BY FIELD1, FIELD2 ASC ;";
//Assert permission for executing the sql string.
perm = new SqlStatementExecutePermission(sql);
perm.assert();
//Prepare the sql statement.
statement = odbcConnection.createStatement();
resultSet = statement.executeQuery(sql);
//Cause the sql statement to run,
//then loop through each row in the result.
while (resultSet.next())
{
//It is not possible to get field 3 and then 1.
//Always get fields in numerical order, such as 1 then 2 the 3 etc.
print resultSet.getString(1);
print resultSet.getString(3);
}
//Close the connection.
resultSet.close();
statement.close();
}
else
{
error("Failed to log on to the database through ODBC.");
}
}
