Example 11 with CharType

use of io.trino.spi.type.CharType in project trino by trinodb.

the class LogicalPlanner method noTruncationCast.

/*
    According to the standard, for the purpose of store assignment (INSERT),
    no non-space characters of a character string, and no non-zero octets
    of a binary string must be lost when the inserted value is truncated to
    fit in the target column type.
    The following method returns a cast from source type to target type
    with a guarantee of no illegal truncation.
    TODO Once BINARY and parametric VARBINARY types are supported, they should be handled here.
    TODO This workaround is insufficient to handle structural types
