Retrieve all Indexes for a given Table with JDBC

Question

I want to write a SpringBatch Tasklet, that automatically activates or de-activates all indexes for a given database table. The code needs to work independantly of the DBMS

Answer 1

You have to make a difference between primary keys (using DatabaseMetaData.getPrimaryKeys() to retrieve) and other indexes (via dbMetaData.getIndexInfo(null, null, tableName, true, false)).
In your loop use:

• rs.getString("INDEX_NAME") to extract index name
• rs.getBoolean("NON_UNIQUE") to extract unique information
• rs.getShort("TYPE") to extract index type
• rs.getInt("ORDINAL_POSITION") to extract ordinal position

Use ORDINAL_POSITION as key break (when current value is <= of previous one) to detect index change.
