Example 1 with CCJSqlParserDefaultVisitor

use of net.sf.jsqlparser.parser.CCJSqlParserDefaultVisitor in project JSqlParser by JSQLParser.

the class CreateViewDeParserTest method testCreateViewASTNode.

@Test
public void testCreateViewASTNode() throws JSQLParserException {
    String sql = "CREATE VIEW test AS SELECT a, b FROM mytable";
    final StringBuilder b = new StringBuilder(sql);
    SimpleNode node = (SimpleNode) CCJSqlParserUtil.parseAST(sql);
    node.dump("*");
    assertEquals(CCJSqlParserTreeConstants.JJTSTATEMENT, node.getId());
    node.jjtAccept(new CCJSqlParserDefaultVisitor() {

        int idxDelta = 0;

        @Override
        public Object visit(SimpleNode node, Object data) {
            if (CCJSqlParserTreeConstants.JJTCOLUMN == node.getId()) {
                b.insert(node.jjtGetFirstToken().beginColumn - 1 + idxDelta, '"');
                idxDelta++;
                b.insert(node.jjtGetLastToken().endColumn + idxDelta, '"');
