MySQL into outfile formatting

问题 select * INTO OUTFILE 'outfile.txt' FIELDS TERMINATED by ',' LINES TERMINATED BY '\n' from nGrams Is there any way I can modify this query to return each row on one line? 回答1: Seems like thats exactly what it would do already. However, if you are doing this on Windows, you might want to use LINES TERMINATED BY '\r\n' or some crappy text editors (e.g. notepad) might not see \n by itself as a line break 来源： https://stackoverflow.com/questions/13750970/mysql-into-outfile-formatting

问题 I am trying to insert data from one table to another with same structure, select * into tbltable1 from tbltable1_Link I am getting the following error message: There is already an object named 'tbltable1' in the database. 回答1: The SELECT INTO statement creates a new table of the name you provide and populates it with the results of the SELECT statement. I think you should be using INSERT INTO since the table already exists. If your purpose is in fact to populate a temporary table, then you

MS Access 2010 SQL Select Into Calculated Column Issue

由 天涯浪子 提交于 2019-12-02 05:17:11
问题 I have a pretty extensive Union query with calculated columns that I'm trying to just "paste values" into a table through a separate SELECT INTO query. I get the error below when executing the query. Is there any way around this without using VBA? “Calculated columns are not allowed in SELECT INTO statements.” For context: Normally, I'd be able to link up to the union query through PowerPivot in Excel but for some reason PowerPivot does not recognize the union query. If I export the union

As I found SELECT * FROM t INTO my_data; works only if: DO $$ DECLARE my_data t%ROWTYPE; BEGIN SELECT * FROM t INTO my_data WHERE id = ?; END $$; Am I right?

问题 Say table1 and table2 already exist, is there any difference between these queries query1 :- select * into table1 from table2 where 1=1 query2: - insert into table1 select * from table2 回答1: The select * into table1 from table2 where 1=1 creates table1 and inserts the values of table2 in them. So, if the table is already created that statement would give an error. The insert into table1 select * from table2 only inserts the values of table2 in table1. 回答2: The first one (SELECT INTO) will
