Class Statement (2.56.0)

A SQL statement that can be executed by calling com.google.cloud.bigtable.data.v2.BigtableDataClient#executeQuery(Statement).

A statement contains a SQL string and optional parameters. A parameterized query should contain placeholders in the form of @ followed by the parameter name. Parameter names may consist of any combination of letters, numbers, and underscores.

Parameters can appear anywhere that a literal value is expected. The same parameter name can be used more than once, for example: WHERE cf["qualifier1"] = @value OR cf["qualifier2"] = @value

It is an error to execute an SQL query with placeholders for unset parameters.

Parameterized Statements are constructed using a Builder and calling setTypeParam(String paramName, Type value) for the appropriate type. For example:

 Statement statement = Statement
     .newBuilder("SELECT cf[@qualifer] FROM table WHERE _key=@key")
     .setBytesParam("qualifier", ByteString.copyFromUtf8("test"))
     .setBytesParam("key", ByteString.copyFromUtf8("testKey"))
     .build();
