可以通过instr函数和substr函数做一个分割函数,将分割后的数据依次输出,而不是这种通过输出窗口才能看到的方法 下图为分割函数主方法,用了insrt函数,substr函数和Oracle的管道函数,管道函数具体设置见这里 具体实现部分如下: CREATEORREPLACEFUNCTIONtest_Row_pipelined(p_insvarinvarchar2, p_delimiterinvarchar2)returntest...
Summary: in this tutorial, you will learn how to use the OracleREGEXP_INSTR()function to search for a substring in a string using a regular expression pattern. Introduction to Oracle REGEXP_INSTR() function# TheREGEXP_INSTR()function enhances the functionality of theINSTR()function by allowing...
The Oracle INSTR function is used to search for a substring within a string and return the position of the substring. It is commonly utilized in SQL queries to locate specific text fragments, analyze text data, or validate strings. The function returns an integer indicating the position of the...
is a nonzero integer that specifies where in the string theINSTR()function begins to search. Thestart_positionis calculated using characters as defined by the input character set. If thestart_positionis positive, thenINSTR()function searches and counts forward from the beginning of the string. I...
