Examples with DatabaseStore org.teiid.query.metadata.DatabaseStore used on opensource projects

Example 1 with DatabaseStore

use of org.teiid.query.metadata.DatabaseStore in project teiid by teiid.

the class DdlPlan method alterProcedureDefinition.

public static void alterProcedureDefinition(final VDBMetaData vdb, final Procedure p, final String sql, boolean updateStore) {
    TransformationMetadata metadata = vdb.getAttachment(TransformationMetadata.class);
    DatabaseStore store = vdb.getAttachment(DatabaseStore.class);
    try {
        Command command = QueryParser.getQueryParser().parseProcedure(p.getQueryPlan(), false);
        QueryResolver.resolveCommand(command, new GroupSymbol(p.getFullName()), Command.TYPE_STORED_PROCEDURE, metadata, false);
        MetadataValidator.determineDependencies(p, command);
    } catch (TeiidException e) {
    // should have been caught in validation, but this logic
    // is also not mature so since there is no lock on the vdb
    // it is possible that the plan is no longer valid at this point due
    // to a concurrent execution
    }
    p.setQueryPlan(sql);
    p.setLastModified(System.currentTimeMillis());
    // $NON-NLS-1$
    metadata.addToMetadataCache(p, "transformation/" + StoredProcedure.class.getSimpleName().toUpperCase(), null);
}

Example 2 with DatabaseStore

    TransformationMetadata metadata = vdb.getAttachment(TransformationMetadata.class);
    DatabaseStore store = vdb.getAttachment(DatabaseStore.class);
    try {
        Command command = QueryParser.getQueryParser().parseCommand(t.getSelectTransformation());
        QueryResolver.resolveCommand(command, metadata);
        MetadataValidator.determineDependencies(t, command);
    } catch (TeiidException e) {
    // should have been caught in validation, but this logic
    // is also not mature so since there is no lock on the vdb
