From AdempiereWiki

1. Use String Buffer

• Make use of String Buffer when writing sql statements

 E.g.:   String strSQL = new String ("SELECT fieldname");
           strSQL.append("FROM tablename");
           strSQL.append("WHERE criteria");

• Check the Java Api for reference

2. Parameterization of SQL Statements

• Make use of parameterized sql statements

3. Conversion of SQL Statements

• Do not use Oracle Conventions for writing SQL Statements

 For e.g.: NVL, +, || ||

• Learn SQL 92 Syntax for database dependencies
• Make use of a single standard for date and time

 For e.g. Either 01/01/2007 12:00:00 or 01-Jan-2007 12:00:00
