Cast to String Column Transform

Returns a transform that casts any column to a character/VARCHAR type. Useful when a numeric or date column needs to be compared as text. The result can be passed as the transform argument to il_compare() or il_block_on(), and composed with other transforms via il_transform(). On DuckDB and PostgreSQL, maps to SQL CAST(col AS VARCHAR).

Usage

il_cast_to_string()

Value

An il_column_transform closure.

Examples

tf <- il_cast_to_string()
tf(c(12345L, 67890L))
#> [1] "12345" "67890"
