Package tech.harmonysoft.oss.sql.dsl.target

Class SqlTarget.Placeholder

  • All Implemented Interfaces:
    
public final class SqlTarget.Placeholder
extends SqlTarget

    Sometimes we need very flexible DSL container to hold generic value. For example, JDBC prepared statements use syntax like update table set column = ? where <condition>. Here ? is a placeholder which doesn't exist in SQL, but is used in specific context (JDBC). We need to handle it if we implement various JDBC operations on top of SQL DSL.

    This class stands for such placeholder
