The embodiment of the invention provides a data query method and device. The data query method comprises the steps of obtaining a structured query language (SQL) statement; determining a command keyword, a query keyword, query data and a target file name in the SQL statement; determining a linux command corresponding to the SQL statement according to the command keyword, the query keyword and the query data, wherein the linux command is formed by combining an awk language and a shell command; formatting data in a target file corresponding the target file name according to the target file name and obtaining a formatted target file; executing the linux command to the formatted target file. When the SQL statement is used for conducting query operation on text information, the SQL statement is mapped into the corresponding awk language and shell command combination so as to achieve text information query operation.
