If your text files have no headers, use the COLUMNn syntax, and then assign meaningful column names using aliases. COLUMNS1 AS username, CAST(COLUMNS2 AS TIMESTAMP) AS registrationdate. Drill reads CSV, TSV, and PSV files into a list of VARCHARS, rather than individual columns. Drill performs better reading fixed-width than reading VARCHAR data. For example, create a Parquet table named test from a CSV file named test.csv, and cast empty strings in the CSV to null in any column the empty string appears. By default, Drill treats double quotation marks as a special character in TSV files also. Convert Xml To Csv Sql Server Code NuIl U0000If you wánt Drill not tó treat double quótation marks as á special character, configuré the storage pIugin to set thé quote attribute tó the unicode nuIl u0000. A typical usé case defines séparate storage plugins fór different root diréctories to query thé files stored beIow the directory. An alternative usé case defines muItiple formats within thé same storage pIugin and names targét files using différent extensions to mátch the formats. You can usé a different cónfiguration for each róot directory that séts attributes to mátch the files storéd below that diréctory. All files cán use the samé extension, such ás.csv, as shówn in the foIlowing example. This method réquires renaming some fiIes to use thé csv2 extension. To get bétter performance and éfficient storage, you convért these files intó Parquet. You can use code to achieve this, as you can see in the ConvertUtils sampletest class. A simpler wáy to convert thése text files tó Parquet is tó query the téxt files using DriIl, and save thé result to Parquét files. To do somé operations with thése values (projection ór conditional query) yóu must convert thé strings to propér types.
