Example 45 with Table

use of org.apache.beam.vendor.calcite.v1_28_0.org.apache.calcite.schema.Table in project beam by apache.

the class RelConverter method createOneRow.

// This function creates a single dummy input row for queries that don't read from a table.
// For example: SELECT "hello"
// The code is copy-pasted from Calcite's LogicalValues.createOneRow() with a single line
// change: SqlTypeName.INTEGER replaced by SqlTypeName.BIGINT.
// Would like to call LogicalValues.createOneRow() directly, but it uses type SqlTypeName.INTEGER
// which corresponds to TypeKind.TYPE_INT32 in ZetaSQL, a type not supported in ZetaSQL
// PRODUCT_EXTERNAL mode. See
// https://github.com/google/zetasql/blob/c610a21ffdc110293c1c7bd255a2674ebc7ec7a8/java/com/google/zetasql/TypeFactory.java#L61
