# batchUpsert

fun <T : Table, E : Any> T.batchUpsert(data: Iterable<E>, vararg keys: Column<*>, onUpdate: UpsertBuilder.(UpdateStatement) -> Unit? = null, onUpdateExclude: List<Column<*>>? = null, where: () -> Op<Boolean>? = null, shouldReturnGeneratedValues: Boolean = true, body: BatchUpsertStatement.(E) -> Unit): List<ResultRow>

Represents the SQL statement that either batch inserts new rows into a table, or updates the existing rows if insertions violate unique constraints.

#### Parameters

data

Collection of values to use in batch upsert.

keys

(optional) Columns to include in the condition that determines a unique constraint match. If no columns are provided, primary keys will be used. If the table does not have any primary keys, the first unique index will be attempted.

onUpdate

Lambda block with an UpdateStatement as its argument, allowing values to be assigned to the UPDATE clause. To specify manually that the insert value should be used when updating a column, for example within an expression or function, invoke `insertValue()` with the desired column as the function argument. If left null, all columns will be updated with the values provided for the insert.

onUpdateExclude

List of specific columns to exclude from updating. If left null, all columns will be updated with the values provided for the insert.

where

Condition that determines which rows to update, if a unique violation is found.

shouldReturnGeneratedValues

Specifies whether newly generated values (for example, auto-incremented IDs) should be returned. See Batch Insert for more details.
