   • what are the data types allowed with the sqoop option "--map-column-java"?

     Top Answer

     Answered May 14, 2019 · 0 votes

     It's pretty taught to load from database into parquet through sqoop, keeping the source datatypes, from the datatypes point of view. For example, you can't load timestamp because it's not supported.

     I'm suggesting you the next workaround:

     • Load with sqoop with all the datatypes string;
     • Insert from table 1 (with all the datatypes string) into table 2, using cast (as timestamp, as decimal ... etc);

     Example:

     --map-column-java "ID=String,NR_CARD=String,TIP_CARD_ID=String,CONT_CURENT_ID=String,AUTORIZ_CONTURI_ID=String,TIP_STARE_ID=String,DATA_STARE=String,COMIS=String,BUGETARI_ID=String,DATA_SOLICITARII=String,DATA_EMITERII=String,DATA_VALABILITATII=String,TIP_DESCOPERIT_ID=String,BRANCH_CODE_EMIT=String,ORG_ID=String,DATA_REGEN=String,FIRMA_ID=String,VOUCHER_BLOC=String,CANAL_CERERE=String,CODE_BUG_OPER=String,CREATED_BY=String,CREATION_DATE=String,LAST_UPDATED_BY=String,LAST_UPDATE_DATE=String,LAST_UPDATE_LOGIN=String,IDPAN=String,MOTIV_STARE_ID=String,DATA_ACTIVARII=String" \-

     In this way you will have all the datatypes, correctly loaded from source.

   • What are the data types in Prolog?

     Top Answer

     Answered Mar 31, 2016 · 22 votes

     I'll bite: Prolog has a single data type term. Not very useful answer, eh?

     Terms are subdivided into

     foo(1,2,3).-

     • Variables. A placeholder, not unified to any specific term. Variables are identified by symbols matching the regular expression [A-Z_][A-Za-z_0-9]* . The variable _ is special: it is the anonymous variable. Every occurrence of _ denotes a distinct variable. For instance, given the fact, foo(1,2,3).A test like foo(_,_,_). will succeed whereas a test like foo(A,A,A). will fail.Once a variable is unified with (bound to) a value, however, it ceases to be variable: unless undone by backtracking it is forever and always what it unified with.
     • Numbers are either float or integer . Usual sorts of rules apply (e.g. -321 is an integer, -321.0 or something like -3.21e+02 is a float.
     • Atoms are names, usually denoted by by a word beginning with a lower-case letter (e.g. atom ), matching the regular rexpression [a-z][A-Za-z0-9_]* . Alternatively, atoms may be delimited by apostrophes (e.g., 'atom' ), which conveniently allow the use of characters not otherwise allowable. The syntax for atom is somewhat more complex than that: essentially anything that doesn't fall into another category will form an atom (e.g., the special atom [] denoting the empty list and the comma ( , ) denoting conjunction are all atoms.
     • Everything else is essentially a structure i.e. tuples of terms, tagged by a functor (a name matching the rules for an atom) with an arity (number of arguments). One can even treat atoms as structure of arity 0.

     There is syntactic sugar poured on top of prolog's other "data types":

     • Lists are denoted by the structure ./2 , with the left-hand argument being the head of the list and the right-hand its tail. The empty list being denoted by the atom [] . For instance, the list [a] is internally represented as .(a,[]),
     • the list [a,b] as .(a,.(b,[])) and
     • the list [a,b|[c]] as .(a,.(b,.(c,[]))).

     One should note that one can write a list using either notation: they will unify appropriately. You can see the attraction of using the bracketed list notation, however.

     Similar syntactic sugar is applied to strings. A string can be written as a string of text delimited by double-quotes: "The cat and the hat". Internally however, strings are represented as lists of integers representing the code points for each of the characters in the implementations internal encoding. For instance, the string "cat" is internally represented (in ASCII/UTF-8) as the list [99,97,116]. "cat" is easier to read, eh?

   • What are the Data types that SASS supports ?

     Sass is a CSS pre-processor scripting language. Here, we don’t need to confuse Sass and Scss, both are the same things but Sass holds older syntax before CSS3 & after CSS3 it is known as SCSS. Likewise all other programming languages, Sass also contains data types to work with different kinds of data that are being used. However, Sass is not a standard programming language but it does consist of data types. In this article, we will look at all the available data types used in Sass & also look for some use-cases. If you don’t know about SASS, please refer to SASS Introduction & SASS full form articles. Sass contains a total of 7 data types: 

     • Numbers
     • Booleans
     • Lists
     • Maps
     • Null
     • String
     • Colors

     Let’s discuss each data type in a sequence.

     Numbers: Sass consider the Number as integers and real numbers together, at the time of use, it does recognize which values are being used. There are some standard units that are used as px(pixels unit) or em(ephemeral unit). In order to perform an operation on numbers then we...

   • What are the data types for which it is not possible to create an array?

     In C, it is possible to have array of all types except following. 1) void. 2) functions.

     For example, below program throws compiler error

     -int main(){ void arr[100];}

     Output:

     error: declaration of 'arr' as array of voids

     But we can have array of void pointers and function pointers. The below program works fine.

     -int main(){ void *arr[100];}

     See examples of function pointers for details of array function pointers.

   A data type is a classification of data which tells the compiler or interpreter how the programmer intends to use the data. Most programming languages support various types of data, including integer, real, character or string, and Boolean.

   What are the different types of data types?

   • Data types may be categorized according to several factors: Primitive data types or built-in data types are types that are built-in to a language implementation. User-defined data types are non-primitive types. For example, Java's numeric types are primitive, while classes are user-defined.

   What is the purpose of data types?

   • The purpose of data types in high-level programming languages is to show the program what sort of content it can expect – they can also be used to test whether a certain variable contains a type of content (like a special character in a number type). Data types are names for fields in databases, into which info for records is entered.
