Class SqlBinaryValue

java.lang.Object

org.springframework.jdbc.core.support.SqlBinaryValue

All Implemented Interfaces:

SqlTypeValue

public class SqlBinaryValue
extends Object
implements SqlTypeValue

Object to represent a binary parameter value for a SQL statement, for example, a binary stream for a BLOB or a LONGVARBINARY or PostgreSQL BYTEA column.

Designed for use with JdbcTemplate as well as JdbcClient, to be passed in as a parameter value wrapping the target content value. Can be combined with SqlParameterValue for specifying a SQL type, for example, new SqlParameterValue(Types.BLOB, new SqlBinaryValue(myContent)). With most database drivers, the type hint is not actually necessary.

Since:

6.1.4
