I have a query which runs fine in Oracle. But when I try to run same query in MySQL, it give me error. Query: ALTER TABLE My_Table ADD TEST_TABLE CLOB; Error: ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version...
CLOB和BLOB其实在RMDBS中最终都是以二进制流进行存储的。最大的差别在于，CLOB有字符集的概念，在从存储...
而SQLServer中的text字段就很方便,可以直接拿来与需要的字符串比对,象什么等于呀小于呀Like呀不在话下。可是换成Oracle就麻烦死了,要开辟一个缓存,把内容一段段读取出来后转换,难道写个where条件都这么复杂?经过多方寻求资料,终于发现一个方便简单的方法:利用dbms_lob包中的方法(放心,内置的)instr和substr。具体的...
全文索引可以对存储在SQL Server数据库中的文本数据执行快速检索功能。同LIKE谓词不同,全文索引只对字符模式进行操作,对字和语句执行搜索功能。全文索引对于查询非结构化数据非常有效。一般情况下,可以对char、varchar和nvarchar数据类型的列创建全文索引,同时,还可以对二进制格式的列创建索引,如image和varbinary数据类型列...
