BatchUpsertStatement

open class BatchUpsertStatement(table: Table, val keys: Column<*>, val onUpdateExclude: List<Column<*>>?, val where: Op<Boolean>?, shouldReturnGeneratedValues: Boolean = true) : BaseBatchInsertStatement, UpsertBuilder

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

Parameters

table

Table to either insert values into or update values from.

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.

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. This clause may not be supported by all vendors.

shouldReturnGeneratedValues

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

isIgnore

val isIgnore: Boolean

keys

val keys: Array<out Column<*>>

val targets: List<Table>

type

val type: StatementType

where

Functions

addBatch

fun addBatch()

Adds the most recent batch to the current list of insert statements.

arguments

open override fun arguments(): List<Iterable<Pair<IColumnType<*>, Any?>>>

Returns all mappings of columns and expression types to their values needed to prepare an SQL statement.

contains

open operator fun contains(column: Column<*>): Boolean

execute

fun execute(transaction: Transaction): Int?

Executes the SQL statement directly in the provided transaction and returns the generated result, or null if either no result was retrieved or if the transaction blocked statement execution.

executeInternal

open override fun PreparedStatementApi.executeInternal(transaction: Transaction): Int

Determines the exact way that an SQL statement is executed in a transaction and applies any necessary logic before returning the result generated by the executed statement.

get

infix operator fun <T> get(column: Column<T>): T

infix operator fun <T> get(column: CompositeColumn<T>): T

getOrNull

fun <T> getOrNull(column: Column<T>): T?

Returns the value of a given column from the first stored ResultRow, or null if either no results were retrieved from the database or if the column cannot be found in the row.

insertValue

open fun <T> insertValue(column: Column<T>): ExpressionWithColumnType<T>

Specifies that this column should be updated using the same values that would be inserted if there was no violation of a unique constraint in an upsert statement.

prepared

open override fun prepared(transaction: Transaction, sql: String): PreparedStatementApi

Uses a transaction connection and an sql string representation to return a precompiled SQL statement, stored as an implementation of PreparedStatementApi.

prepareSQL

open override fun prepareSQL(transaction: Transaction, prepared: Boolean): String

Returns the string representation of an SQL statement.

set

open operator override fun <S> set(column: Column<S>, value: S)

open operator fun <T, S : T?, E : Expression<S>> set(column: Column<T>, value: E)

open operator fun <S> set(column: Column<S>, value: Query)

@JvmName(name = "setWithEntityIdExpression")

operator fun <S, ID : EntityID<S>, E : Expression<S>> set(column: Column<ID>, value: E)

@JvmName(name = "setWithNullableEntityIdValue")

operator fun <S : Comparable<S>> set(column: Column<EntityID<S>?>, value: S?)

@JvmName(name = "setWithEntityIdValue")

operator fun <S : Comparable<S>> set(column: Column<EntityID<S>>, value: S)

open operator fun <S> set(column: CompositeColumn<S>, value: S)

storeUpdateValues

open fun storeUpdateValues(onUpdate: UpsertBuilder.(UpdateStatement) -> Unit)

Calls the specified function onUpdate with an UpdateStatement as its argument, allowing values to be stored as part of the UPDATE clause of the upsert statement associated with this builder.

update

open fun <T, S : T?> update(column: Column<T>, value: SqlExpressionBuilder.() -> Expression<S>)

Updates the mapping of the specified column with the value of the provided expression.

open fun <T, S : T?> update(column: Column<T>, value: Expression<S>)

Updates the mapping of the specified column with the specified value if column has not been previously set up for a change and if value is of a valid type.
