Trouvez une valeur n'importe où dans une base de données

Étant donné un #, comment puis-je découvrir dans quelle table et colonne il peut être trouvé?

Je m'en fiche si c'est rapide, il faut juste que ça marche.

Cela pourrait vous aider . - de Narayana Vyas. Il recherche toutes les colonnes de toutes les tables d'une base de données donnée. Je l'ai déjà utilisé et ça marche.

Il s'agit du processus stocké du lien ci-dessus - la seule modification que j'ai apportée a été de remplacer la table temporaire par une variable de table afin que vous n'ayez pas à vous souvenir de la supprimer à chaque fois.

Si vous ne devez exécuter une telle recherche qu'une seule fois, vous pouvez probablement utiliser l'un des scripts déjà présentés dans d'autres réponses. Mais sinon, je recommanderais d'utiliser ApexSQL Search pour cela. C'est un complément SSMS gratuit et cela m'a vraiment fait gagner beaucoup de temps.

Avant d'exécuter l'un des scripts, vous devez le personnaliser en fonction du type de données que vous souhaitez rechercher. Si vous savez que vous recherchez une colonne datetime, il n'est pas nécessaire de rechercher dans les colonnes nvarchar. Cela accélérera toutes les requêtes ci-dessus.

Sur la base de la réponse de bnkdev, j'ai modifié le code de Narayana pour rechercher toutes les colonnes, même numériques.

Cela fonctionnera plus lentement, mais cette version trouve en fait toutes les correspondances, pas seulement celles trouvées dans les colonnes de texte.

Je ne remercierai jamais assez ce type. M'a sauvé des jours de recherche à la main!

C'est mon opinion indépendante sur cette question que j'utilise pour mon propre travail. Il fonctionne dans SQL 2000 et versions ultérieures, permet les caractères génériques, le filtrage des colonnes et recherche la plupart des types de données normaux.

Merci pour le script vraiment utile.

Vous devrez peut-être ajouter la modification suivante au code si vos tables ont des champs non convertibles:

SET @ColumnName =
    (
        SELECT MIN(QUOTENAME(COLUMN_NAME))
        FROM    INFORMATION_SCHEMA.COLUMNS
        WHERE       TABLE_SCHEMA    = PARSENAME(@TableName, 2)
            AND TABLE_NAME  = PARSENAME(@TableName, 1)
            AND DATA_TYPE NOT IN ('text', 'image', 'ntext')                 
            AND QUOTENAME(COLUMN_NAME) > @ColumnName
    )

J'ai écrit une fois un outil pour moi-même pour faire exactement cette chose:

a7 SqlTools

C'est gratuit et open-source:

Ici, une solution très douce et petite:

1) create a store procedure:

create procedure get_table
@find_str varchar(50)

==========================

2) call procedure by calling store procedure:
exec get_table 'serach_string';

Une autre façon d'utiliser JOIN et CURSOR:

USE My_Database;

-- Store results in a local temp table so that.  I'm using a
-- local temp table so that I can access it in SP_EXECUTESQL.
create table #tmp (
    tbl nvarchar(max),
    col nvarchar(max),
    val nvarchar(max)   
);

declare @tbl nvarchar(max);
declare @col nvarchar(max);
declare @q nvarchar(max);
declare @search nvarchar(max) = 'my search key';

-- Create a cursor on all columns in the database
declare c cursor for
SELECT tbls.TABLE_NAME, cols.COLUMN_NAME  FROM INFORMATION_SCHEMA.TABLES AS tbls
JOIN INFORMATION_SCHEMA.COLUMNS AS cols
ON tbls.TABLE_NAME = cols.TABLE_NAME

-- For each table and column pair, see if the search value exists.
open c
fetch next from c into @tbl, @col
while @@FETCH_STATUS = 0
begin
    -- Look for the search key in current table column and if found add it to the results.
    SET @q = 'INSERT INTO #tmp SELECT ''' + @tbl + ''', ''' + @col + ''', ' + @col + ' FROM ' + @tbl + ' WHERE ' + @col + ' LIKE ''%' + @search + '%'''
    EXEC SP_EXECUTESQL @q
    fetch next from c into @tbl, @col
end
close c
deallocate c

-- Get results
select * from #tmp

-- Remove local temp table.
drop table #tmp

Vous devrez peut-être créer un index inversé pour votre base de données. Il est assuré d'être assez rapide.

Supposons que si vous voulez obtenir toute la table avec un nom, un nom de colonne contienne logintime dans la base de données MyDatabase ci-dessous est l'exemple de code

    use MyDatabase

    SELECT t.name AS table_name,
    SCHEMA_NAME(schema_id) AS schema_name,
    c.name AS column_name
    FROM sys.tables AS t
    INNER JOIN sys.columns c ON t.OBJECT_ID = c.OBJECT_ID
    WHERE c.name LIKE '%logintime%'
    ORDER BY schema_name, table_name;

Si vous avez installé phpMyAdmin, utilisez sa fonction de recherche .

Sélectionnez votre DataBase.

Assurez-vous d'avoir sélectionné DataBase, pas une table, sinon vous obtiendrez une boîte de dialogue de recherche complètement différente.

1. Cliquez sur l' onglet Recherche
2. Élément de liste Choisissez le terme de recherche que vous souhaitez

À des fins de développement, vous pouvez simplement exporter les données des tableaux requis dans un seul HTML et effectuer une recherche directe dessus.

Les outils clients de base de données (comme DBeaver ou phpMyAdmin ) prennent souvent en charge les moyens de recherche en texte intégral dans toute la base de données.
