,LoaderLoadStep<R>
Loader
API is used for configuring data loads.
The step in constructing the Loader
object where you can set the
optional CSV loader options.
Referencing XYZ*Step
types directly from client code
It is usually not recommended to reference any XYZ*Step
types
directly from client code, or assign them to local variables. When writing
dynamic SQL, creating a statement's components dynamically, and passing them
to the DSL API statically is usually a better choice. See the manual's
section about dynamic SQL for details: https://www.jooq.org/doc/latest/manual/sql-building/dynamic-sql.
Drawbacks of referencing the XYZ*Step
types directly:
- They're operating on mutable implementations (as of jOOQ 3.x)
- They're less composable and not easy to get right when dynamic SQL gets complex
- They're less readable
- They might have binary incompatible changes between minor releases

Method Details
-
ignoreRows
Specify that a certain number of rows should be ignored from the CSV file. This is useful for skipping processing informationBy default, this is set to
1
, as CSV files are expected to hold a header row.- Parameters:
number
- The number of rows to ignore.
-
quote
Specify the quote character. By default, this is"
-
separator
Specify the separator character. By default, this is,
-
nullString
Specify the input string representation ofNULL
.By default, this is set to
null
, which means that all empty strings are loaded into the database as such. In some databases (e.g.SQLDialect.ORACLE
), this is effectively the same as loadingNULL
.In order to treat empty strings as
null
, you can set thenullString
to""
. If the null string is overridden with something like{null}
, for instance, then empty strings will also be loaded as such by jOOQ.
