1, mysql command to import
grammar:
mysql -u root -p passwd < runoob.sql
2, source command to import
source aa.sql
3, load data import data using
MySQL provides a LOAD DATA INFILE statement to insert the data. The following examples will read files in the current directory dump.txt, inserting the data file to the current mytbl table in the database.
mysql> LOAD DATA LOCAL INFILE 'dump.txt' INTO TABLE mytbl;
If you specify LOCAL keyword, read files from the client indicates that the host by path. If not specified, the file on the server reads the file by path.
Can you clear that in the LOAD DATA statement delimiters and line marker column value, but the defaults are tab and newline.
The syntax of the FIELDS and LINES clauses two commands are the same. Two clauses are optional, but if the two are simultaneously specified, FIELDS clause must appear before the LINES clause.
If the user specifies a FIELDS clause, its clauses (TERMINATED BY, [OPTIONALLY] ENCLOSED BY and ESCAPED BY) is also optional, however, the user must specify at least one of them.
mysql> LOAD DATA LOCAL INFILE 'dump.txt' INTO TABLE mytbl
-> FIELDS TERMINATED BY ':' -> LINES TERMINATED BY '\r\n';
LOAD DATA default data is inserted in the order of the data file and, if not the column in the data file is inserted into the table columns, the columns in the order specified is required.
For example, the order of columns in the data file is a, b, c, but in order to insert the table columns b, c, a, the data import syntax is as follows:
MySQL > the LOAD the DATA INFILE the LOCAL 'dump.txt' -> the INTO TABLE MyTbl ( B , C , A ); . 4, import data using mysqlimport
mysqlimport client provides a command LOAD DATA INFILEQL statement line interface. Most options to mysqlimport correspond directly to LOAD DATA INFILE clause.
Dump.txt in the import file data from the data table to mytbl, use the following command:
$ mysqlimport -u root -p --local mytbl dump.txt password *****
mysqlimport command to specify the option to set the specified format command statement format is as follows:
$ mysqlimport -u root -p --local --fields-terminated-by=":" \ --lines-terminated-by="\r\n" mytbl dump.txt password *****
mysqlimport statement --columns use option to set the order of columns:
$ mysqlimport -u root -p --local --columns=b,c,a \ mytbl dump.txt password *****
