Example 2 with JdbcQuery

use of org.apache.ignite.internal.processors.odbc.jdbc.JdbcQuery in project ignite by apache.

the class JdbcThinStatement method addBatch.

/**
 * {@inheritDoc}

Example 3 with JdbcQuery

use of org.apache.ignite.internal.processors.odbc.jdbc.JdbcQuery in project ignite by apache.

the class JdbcThinConnection method addBatch.

/**
 * Add another query for batched execution.
 * @param sql Query.
 * @param args Arguments.
 * @throws SQLException On error.
 */
void addBatch(String sql, List<Object> args) throws SQLException {
    boolean newQry = (args == null || !F.eq(lastStreamQry, sql));
    // Providing null as SQL here allows for recognizing subbatches on server and handling them more efficiently.
    JdbcQuery q = new JdbcQuery(newQry ? sql : null, args != null ? args.toArray() : null);
    if (streamBatch == null)
        streamBatch = new ArrayList<>(streamBatchSize);
