How do I get a list of column names in the ResultSet?
You can get the name of a particular column using the getColumnName() method of the ResultSetMetadata interface. This method accepts an integer value that represents the index of a column and returns a string value that represents the name of the specified column.
rsmdList list = template. query(builder. toString(),new ResultSetExtractor() { @Override public ResultSetMetaData extractData(ResultSet rs) throws SQLException, DataAccessException { ResultSetMetaData rsmd = rs.getMetaData(); return rsmd; } }); ResultSetMetaData rsmd = rsmdList.
Extract information from the table. To get your feed’s metadata, call the getMetaData() method using the Connection object that was created in the last part of this series. Here is some simple code to extract all user defined tables from your data source. The important method that draws attention is the connection.
Using the information schema
- SELECT TABLE_NAME FROM SCHEME_INFORMATION. TABLES.
- SELECT TABLE_NAME, COLUMN_NAME FROM SCHEME_INFO. COLUMNS.
- SELECT COLUMN_NAME FROM SCHEME_INFO. COLUMNS WHERE TABLE_NAME = ‘Album’
- IF EXISTS (SELECT * FROM SCHEME_INFO.
- IF EXISTS (SELECT * FROM SCHEME_INFO.
Metadata is data about data (see those examples to better understand this concept). In the case of relational databases, metadata refers to information about its schema and all other information related to access, storage, built-in programs, or any other information about the elements or use of the database. data.
T-SQL metadata functions in SQL Server are under the umbrella of system functions in SSMS and can be accessed as shown below. Expand Databases and go to Programmability in the AdventureWorksDW2017 database.
Metadata is “the data about the data”. Anything that describes the database, rather than being the content of the database, is metadata. Therefore, column names, database names, user names, version names, and most string output from SHOW are metadata.
Often described as data about data, metadata is a critical building block used to transform data into an asset for the entire enterprise. Simply defined, metadata is the summary and description of your data that is used to classify, organize, label, and understand the data, making it much easier to sort and find data.
Metadata makes spatial information more useful to all kinds of users by making it easier to document and locate data sets. The increasing availability of data of all kinds from many different sources has helped make GIS technology more useful and widely adopted.
Examples of information (this is not an exhaustive list) contained in the metadata are: GIS data creation date, GIS data author, contact information, source agency, map projection and coordinate system, scale, error , explanation of symbology and attributes, dictionary data, data restrictions and licenses.
