Translates a single SQL statement from one dialect to another

translateSingleStatement translates a single SQL statement from one dialect to another.

translateSingleStatement(
  sql = "",
  targetDialect,
  tempEmulationSchema = getOption("sqlRenderTempEmulationSchema"),
  oracleTempSchema = NULL
)

Arguments

sql

The SQL to be translated

targetDialect

The target dialect. Currently "oracle", "postgresql", "pdw", "impala", "sqlite", "sqlite extended", "netezza", "bigquery", "snowflake", "synapse", "spark", "redshift", and "iris" are supported.

tempEmulationSchema

Some database platforms like Oracle and Impala do not truly support temp tables. To emulate temp tables, provide a schema with write privileges where temp tables can be created.

oracleTempSchema

DEPRECATED: use tempEmulationSchema instead.

Value

A character vector with the translated SQL.

Details

This function takes SQL in one dialect and translates it into another. It uses simple pattern replacement, so its functionality is limited. This removes any trailing semicolon as required by Oracle when sending through JDBC. An error is thrown if more than one statement is encountered in the SQL.

Examples

translateSingleStatement("USE my_schema;", targetDialect = "oracle")
#> [1] "ALTER SESSION SET current_schema = my_schema"
#> attr(,"sqlDialect")
#> [1] "oracle"
