    • getFormattedJdbcPlaceholder

      public String getFormattedJdbcPlaceholder(BindableColumn<?> column, String prefix, String parameterName)
      Description copied from class: RenderingStrategy
      This method generates a binding for a parameter to a placeholder in a generated SQL statement.

      This binding is appropriate when there can be a mapping between a parameter and a known target column, In MyBatis, the binding can specify type information based on the column. The bindings are specific to the target framework.

      For MyBatis, a binding looks like this: "#{prefix.parameterName,jdbcType=xxx,typeHandler=xxx,javaType=xxx}"

      For Spring, a binding looks like this: ":parameterName"

      Specified by:
      getFormattedJdbcPlaceholder in class RenderingStrategy
      Parameters:
      column - column definition used for generating type details in a MyBatis binding. Ignored for Spring.
      prefix - parameter prefix used for locating the parameters in a SQL provider object. Typically, will be RenderingStrategy.DEFAULT_PARAMETER_PREFIX. This is ignored for Spring.
      parameterName - name of the parameter. Typically generated by calling RenderingStrategy.formatParameterMapKey(AtomicInteger)
      Returns:
      the generated binding

    • getFormattedJdbcPlaceholder

      public String getFormattedJdbcPlaceholder(String prefix, String parameterName)
      Description copied from class: RenderingStrategy
      This method generates a binding for a parameter to a placeholder in a generated SQL statement.

      This binding is appropriate when the parameter is bound to placeholder that is not a known column (such as a limit or offset parameter). The bindings are specific to the target framework.

      For MyBatis, a binding looks like this: "#{prefix.parameterName}"

      For Spring, a binding looks like this: ":parameterName"

      Specified by:
      getFormattedJdbcPlaceholder in class RenderingStrategy
      Parameters:
      prefix - parameter prefix used for locating the parameters in a SQL provider object. Typically, will be RenderingStrategy.DEFAULT_PARAMETER_PREFIX. This is ignored for Spring.
      parameterName - name of the parameter. Typically generated by calling RenderingStrategy.formatParameterMapKey(AtomicInteger)
      Returns:
      the generated binding

    • getRecordBasedInsertBinding

      public String getRecordBasedInsertBinding(BindableColumn<?> column, String prefix, String parameterName)
      Description copied from class: RenderingStrategy
      This method generates a binding for a parameter to a placeholder in a row based insert statement.

      This binding is specifically for use with insert, batch insert, and multirow insert statements. These statements bind parameters to properties of a row class. The Spring implementation changes the binding to match values expected for a these insert statements. For MyBatis, the binding is the same as RenderingStrategy.getFormattedJdbcPlaceholder(BindableColumn, String, String).

      For MyBatis, a binding looks like this: "#{prefix.parameterName,jdbcType=xxx,typeHandler=xxx,javaType=xxx}"

      For Spring, a binding looks like this: ":prefix.parameterName"

      Overrides:
      getRecordBasedInsertBinding in class RenderingStrategy
      Parameters:
      column - column definition used for generating type details in a MyBatis binding. Ignored for Spring.
      prefix - parameter prefix used for locating the parameters in a SQL provider object. Typically, will be either "row" or "records[x]" to match the properties of the generated statement object class.
      parameterName - name of the parameter. Typically, this is a property in the row class associated with the insert statement.
      Returns:
      the generated binding

    • getRecordBasedInsertBinding

      public String getRecordBasedInsertBinding(BindableColumn<?> column, String parameterName)
      Description copied from class: RenderingStrategy
      This method generates a binding for a parameter to a placeholder in a row based insert statement.

      This binding is specifically for use with insert, batch insert, and multirow insert statements and the MapToRow mapping. These statements bind parameters to the row class directly.

      For MyBatis, a binding looks like this: "#{parameterName,jdbcType=xxx,typeHandler=xxx,javaType=xxx}"

      For Spring, a binding looks like this: ":parameterName"

      Specified by:
      getRecordBasedInsertBinding in class RenderingStrategy
      Parameters:
      column - column definition used for generating type details in a MyBatis binding. Ignored for Spring.
      parameterName - name of the parameter. Typically, will be either "row" or "records[x]" to match the properties of the generated statement object class.
      Returns:
      the generated binding
