org.springframework.jdbc.core.SqlTypeValue
Imports
java.io.ByteArrayInputStream, .IOException, .InputStream, java.sql.PreparedStatement, .SQLException, .Types, org.springframework.core.io.InputStreamSource, .Resource, org.springframework.jdbc.core.SqlTypeValue, org.springframework.lang.Nullable
Object to represent a binary parameter value for a SQL statement, e.g. a binary stream for a BLOB or a LONGVARBINARY or PostgreSQL BYTEA column.

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