在使用postgres java驱动程序执行查询时，在输入末尾获取语法错误

Question

以下查询在通过java驱动程序执行时给出错误，而在DBVisualizer上执行时没有错误

SELECT pr.id,
       pr.name,
       CDPC.category_id,
       CDPC.category_depth,
       CDPC.product_count,
       pr.primary_category_id
FROM ics_products_to_include_tmp inc
  INNER JOIN catalog.products pr ON inc.product_id = pr.id
  INNER JOIN catalog.products_in_categories pic ON pic.product_id = pr.id AND pic.active = true
  INNER JOIN catalog.categories CC ON CC.id = pic.category_id AND CC.active = true
  INNER JOIN category_depth_product_count_tmp CDPC 
      ON CDPC.category_id = CC.id 
     AND NOT EXISTS (SELECT *
                     FROM ics_products_cds_ids_tmp cds
                     WHERE cds.product_id = pr.id)
WHERE pr.site_id = '150'
ORDER BY pr.id

这里是错误

    Exception in thread "main" org.postgresql.util.PSQLException: ERROR: syntax error at end of input

Answer 1

请尝试使用以美元为引号的符号。

不要使用pr.site_id='150'来尝试使用类似的方法

pr.site_id = $$150$$

很可能您的JDBC驱动程序在区分两个不同的引号'(')和'(`)时遇到了问题
