The following command generates random SQL statements which match the given pattern.
regstr pattern -n 100 "INSERT INTO tbl\(\`col1\`,\`col2\`\) VALUES \([1-9][0-9]{6},\'[a-z]+\'\);"The output will be:
INSERT INTO tbl(`col1`,`col2`) VALUES (4215641,'xv');
INSERT INTO tbl(`col1`,`col2`) VALUES (1715818,'pscxbudyv');
INSERT INTO tbl(`col1`,`col2`) VALUES (4591517,'mywrubwh');
INSERT INTO tbl(`col1`,`col2`) VALUES (1820287,'bcseumkgho');
INSERT INTO tbl(`col1`,`col2`) VALUES (3963386,'rqtbyg');
INSERT INTO tbl(`col1`,`col2`) VALUES (2163713,'jrddezechfh');
INSERT INTO tbl(`col1`,`col2`) VALUES (9931542,'fw');
INSERT INTO tbl(`col1`,`col2`) VALUES (1163443,'xvkig');
INSERT INTO tbl(`col1`,`col2`) VALUES (7329303,'ccnnuo');
INSERT INTO tbl(`col1`,`col2`) VALUES (4206145,'ab');
...
Example file example/sql.txt has the following content.
INSERT INTO tbl\(`col1`,`col2`\) VALUES \([1-9][0-9]+,'[a-z]+'\);
We can use -i flag to specify the input file from which we can load the regular expression.
regstr pattern -i ./example/sql.txt -n 10 -l 5
The output will be:
INSERT INTO tbl(`col1`,`col2`) VALUES (167476,'c');
INSERT INTO tbl(`col1`,`col2`) VALUES (164539,'ookd');
INSERT INTO tbl(`col1`,`col2`) VALUES (69987,'enla');
