public class SpringBatchReaderRenderingStrategy

Method Details

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"

Overrides:

getFormattedJdbcPlaceholder in class MyBatis3RenderingStrategy

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
