Examples with JdbcParameterBinding org.hibernate.sql.exec.spi.JdbcParameterBinding used on opensource projects

Example 1 with JdbcParameterBinding

use of org.hibernate.sql.exec.spi.JdbcParameterBinding in project hibernate-orm by hibernate.

the class AbstractJdbcParameter method bindParameterValue.

@Override
public void bindParameterValue(PreparedStatement statement, int startPosition, JdbcParameterBindings jdbcParamBindings, ExecutionContext executionContext) throws SQLException {
    final JdbcParameterBinding binding = jdbcParamBindings.getBinding(AbstractJdbcParameter.this);
    if (binding == null) {
        throw new ExecutionException("JDBC parameter value not bound - " + this);
    }
    final Object bindValue = binding.getBindValue();
    JdbcMapping jdbcMapping = binding.getBindType();
    if (jdbcMapping == null) {
        jdbcMapping = this.jdbcMapping;
    }
    // If the parameter type is not known from the context i.e. null or Object, infer it from the bind value
    if (jdbcMapping == null || jdbcMapping.getMappedJavaType().getJavaTypeClass() == Object.class) {
        jdbcMapping = guessBindType(executionContext, bindValue, jdbcMapping);
    }
    bindParameterValue(jdbcMapping, statement, bindValue, startPosition, executionContext);
}

Example 2 with JdbcParameterBinding

    if (parameter == getOffsetParameter()) {
        binding = new JdbcParameterBindingImpl(getIntegerType(), getLimit().getFirstRow());
