Examples with ArrayParser com.google.cloud.spanner.pgadapter.parsers.ArrayParser used on opensource projects

Example 1 with ArrayParser

use of com.google.cloud.spanner.pgadapter.parsers.ArrayParser in project pgadapter by GoogleCloudPlatform.

the class ParserTest method testLongArrayParsing.

@Test
public void testLongArrayParsing() {
    Long[] value = { 1L, 2L, 3L };
    // The binary format of a PG array should contain the OID of the element type and not the array
    // OID. For INT8 that means 20 and not 1016
    // See
    // https://github.com/pgjdbc/pgjdbc/blob/60a81034fd003551fc863033f491b2d0ed1dfa80/pgjdbc/src/main/java/org/postgresql/jdbc/ArrayDecoding.java#L505
    // We can test this more thoroughly when
    // https://github.com/GoogleCloudPlatform/pgadapter/pull/36
    // has been merged.

}

Example 2 with ArrayParser
