Multiple rows can be inserted in a batch by passing an array of structs to insert.
This is not the same as looping over and array and calling insert in the loop. Using an array with insert will batch the inserts in one SQL call. Looping over an array and calling insert each time will create a SQL request for each item in the array. Bottom line, pass your array to insert!
A single column, a list or columns, or an array of columns to return from the inserted query.
returning is only supported in PostgresGrammar and SqlServerGrammar. Using this method on unsupported grammars will result in an UnsupportedOperation exception. Be aware that using this method constrains your grammar choices.
Specifies columns to be returned from the insert query.
A struct or array of structs to insert into or update on the table. If a source is provided, this should be an array of column names to update instead.
target
string | array<string>
true
A column name or array of column names to match the values to the table. If a match is found, the record will be updated. Otherwise, a new record will be inserted. Most database grammars required these columns to have either a primary key or a unique index.
update
array | struct
false
null
Either an array of columns to update using the current value matched or a struct containing the column names as keys and the corresponding to update. If blank, it will update all the columns in the passed in value.
source
function | QueryBuilder
false
null
A callback function or QueryBuilder object to use as the source for the upsert. When using this parameter, values must be an array of column names to update.
deleteUmatched
boolean
false
false
Boolean flag to delete any unmatched source records as part the upsert. (SQL Server only.)
options
boolean
false
{}
Any additional queryExecute options.
toSql
boolean
false
false
If true, returns the raw SQL string instead of running the query. Useful for debugging.
An upsert is a batch operation that either inserts or updates a row depending on if a target match is found. If a row is matched with the target column(s), then the matched row is updated. Otherwise a new row is inserted.
In most database grammars, the target columns are required to be primary key or unique indexes.

The update clause in a upsert can also accept raw values, making it very useful for tracking data like statistics.
MERGE [stats] AS [qb_target]
USING (VALUES (?, ?, ?), (?, ?, ?)) AS [qb_src]
([postId], [viewedDate], [views])
ON [qb_target].[postId] = [qb_src].[postId]
AND [qb_target].[viewedDate] = [qb_src].[viewedDate]
WHEN MATCHED THEN UPDATE
SET [views] = stats.views + 1
WHEN NOT MATCHED BY TARGET THEN INSERT
([postId], [viewedDate], [views])
VALUES
([postId], [viewedDate], [views])
INSERT INTO "stats"
("postId", "viewedDate", "views")
VALUES
(?, ?, ?),
(?, ?, ?)
ON CONFLICT ("postId", "viewedDate") DO UPDATE
"views" = stats.views + 1

SET "VIEWS" = stats.views + 1
WHEN NOT MATCHED THEN INSERT

VALUES
("QB_SRC"."POSTID", "QB_SRC"."VIEWEDDATE", "QB_SRC"."VIEWS")
A source callback or QueryBuilder instance can be used instead of explicit values. This allows you to do upserts across tables or subqueries.
To do this, provide a source that is either a function to configure a new QueryBuilder instance or an already configured QueryBuilder instance. Then specify the columns that will be affected as an array of strings to values.
